"Daniel Perlman — wine lover, inventor and Brandeis University biophysicist — spent three years studying how wine flows across the lip of a wine bottle, causing it to drip."
"After years of research, Perlman found a solution that paid off. (...) Adding a groove around the neck of the bottle, just beneath the lip, creates a barrier. To drip, the wine would have to travel up to go inside the grove — that is, against the force of gravity — or have the momentum needed to jump the groove. Thanks to the laws of physics, the wine droplet cannot cross barrier that the groove creates; instead, the droplet falls from the lip and into the wine glass, along with what is being poured."

3 years of studying wine drip, that's a serious hangover
KrustyPartiallyGelatinatedNonDairyGumBasedBeverage
I solved this years ago by drinking straight from the bottle

Does the various alcohol content affect the surface tension ?
Wineoceros
I usually drink it out of a box...but when I'm feeling classy (or at a restaurant) I hit the bottle & THIS. IS. GENIUS! No drop left behind!
umikaloo
I need this on my dick.
UmHowAboutAnonymous
Also pouring a wine bottle properly prevents it from dripping...
Stuebydoo
I wonder if you can get your cock modified to be non drip...asking for a friend
laestrella
Or just don't pour it like a douche.
Jazek
Or you could just twist the bottle as you finish pouring. Amateur
emilytangerine8910
I’m so glad they’re spending time and resources on suck important problems.
Daemon7777
It took them years to figure this out? It only took me 5s of browsing imgur! Can I get my degree now?
Brokiff
Just the tip

NamelessAndrew
It took him three years to figure that out?
bunnyrut
you twist the bottle as you finish pouring you uncultured swine.

Thhhhhisiissisisisi

That is so cool
TheSneakySloth
I need this in my life!
TeamOneE
Too late.
pyrrhlis
Now make milk jugs like this.
dhaskjdhawyajhdbsdbgwakjhbdnmcckclkklkl
This took him fucking years? what the fuck mate?
kgbofficer
I mean, it was 3 years of drinking wine on the job
MerryJoe
Looks cool, but wouldn't it likely crack under the pressure of the bottle opener?
spicefreak
Wine is corked.
MerryJoe
Oh man, for the life of me I couldn't remember the word "corkscrew" when I wrote thay
DeviatedPrevert
this issue only occurs if you stop pouring
DeviatedPrevert
cant believe i got 100 points for this crappy comment
iwantacorgi
the only issue is pouring it into anything but your mouth
NotABadLookingNarcissist
That's why I only drink wine from a giant novelty glass.
jredwine42
Organic chemistry lab should be required for all. You learn to pour in that class.
RobertEmmet
This made me exclaim out loud: "Outstanding!"
AnAxel
Reads first line: nice research project, drink wine for 3years! Winning!
wilsonsmith
That took him three years? That's seems like more of a think it up during the same bottle of wine you noticed the issue situation
HipHopSaint
When you haven't worked on your thesis all year and it's due in a few weeks
Dustingineer
Same :/
Veggisaurus
That's so much time!!!
TwahaRamadhani
I'm on that sinking boat right now
HipHopSaint
Good luck to you! Mind if I ask what your thesis is for?
iforgotwhatiwasdoinghere
Almost every other type of bottle has a lip to stop the liquid from dripping down. Bottle makers have know this for centuries. Why a thesis?
AwesomeName
If that's true, why are wine bottles still dripping?
iforgotwhatiwasdoinghere
Traditionalists
Tarmaccian
Because you're pouring them incorrectly, without a twist at the end. The dry part of the bottle stops the drip.
SherMattLockSmith
It has a lip, plainly seen on the left bottle, that completely fails to prevent the drip....
iforgotwhatiwasdoinghere
The wide band is a collar for the corker to grab onto. It doesn't affect the liquid coming out. Like with a coffee mug, it just rolls down.
wittykitty
Right, some olive oil bottle caps already come like this
iforgotwhatiwasdoinghere
The cheaper wine bottles with the screw on lids don't drip. The cork blight made them rethink the whole bottling tradition.
HadMeSomeChickens
Because for centuries wine pourers knew to twist the bottle.
iforgotwhatiwasdoinghere
What are you? Some kind of riddler?
TwoCheese
It just says he studied it for 3 years. I don't think it was his thesis. He's a biophysicist.
SirQuasimodo
An engineer would have solved it within an hour.
iforgotwhatiwasdoinghere
Why 3 years of research? It's a problem that has already been solved.
NeutralPitStopCommenter
Obviously not if there's still some bottles with that bug
iforgotwhatiwasdoinghere
Wine bottles need a bug patch.
lunicow
Maybe its to get a better understanding of the physics behind it?
iforgotwhatiwasdoinghere
There's plenty of engineering research on fluid dynamics at openings.
custardmiteofglut
I've always given the bottle a twist as I finish pouring - no drips!
boognish115
Oh so that's what Ray Charles was singing about!
irespondwithsimpsonsquotes
Yep. Classy af. Least that's what I tell myself.
HadMeSomeChickens
Yup, that's how you're supposed to unless you're a philistine.
bunduz
It's how you pour it, and how you serve it. At least you know it.
somecallmetimmmmkay
Right!?? You must have served before? It's how we were trained to provide wine service, a $200 bottle of wine? Not a drop spilled
laketittykaka
You can easily see them twisting the bottle on the right.
kgbofficer
They also raise the bottle at a sharper angle to cut the stream of sooner.
kgbofficer
Not saying the new bottle end doesn't do anything to help, but they did extra in the video to keep it from dripping.
1Plebian
3 years huh. Classic university smarts
cow042
Depends on how many different bottle designs were tested and testing to make sure new design doesnt mess up structure
1234canIhavealittlemore
2.9 years of partying, three months of crazed work and too much coffee. That is how we roll at uni.
barbaavis
Pouring wine for three years sounds pretty SMRT to me
barbaavis
But only if it is drank after, to determine if bottle shape impacts taste
woodjoiner
Most chemical bottles in the chem and bio departments have this. It is a new application not a new idea.
Monstache
"After years of research...", "studying how wine flows (or something)". I think he never saw those then...
woodjoiner
Sounds like poor research if he didn't look into how other bottles are designed when trying to design a bottle.
Monstache
I know right? I feel like David Mitchell and his angry logic thinking about all the hours he spent calculating and looking at the wine flow
Monstache
"How on earth would you just not do trial and error instead of spending years on research? Just fiddle with a bottle neck till it works!"
